PowerColor Expands Go! Green Lineup with Silent Models

Unfortunately go green meas equals go slow these days.

PowerColor expanded its energy efficient lineup of entry-thru-mainstream graphics cards which it calls Go! Green, with two passively-cooled graphics cards based on ATI Radeon HD 4670 and Radeon HD 4350. The PowerColor Go! Green SCS3 HD 4670 uses a large passive cooler which uses heat-pipes to convey heat to a aluminum fin array. This extends the card's footprint to around two expansion slots. The card maintains ATI reference core clock speeds of 750 MHz, and makes use of 1 GB of memory across a 128-bit GDDR3 memory interface, clocked at 1600 MHz. Output connectivity includes DVI, D-Sub, and HDMI. Like every other HD 4670 accelerator, it relies entirely on the PCI-Express slot for its power. Hardware CrossFireX connectivity isn't provided.

PowerColor's second offering, the HD 4350 Go! Green HDMI, unlike most other Radeon HD 4350 graphics cards, is a full-height card, with a monolithic aluminum heatsink that cools the GPU and some of the memory chips. The heatsink, although fit for most half-height cards, spans across two expansion slots. Its USP is the onboard HDMI connector, which neighbours DVI and D-Sub ports. Its core is clocked at 600 MHz, with its 64-bit DDR2 memory at 800 MHz. There are three sub-variants based on memory amount: 256 MB, 512 MB, and 1 GB. PowerColor maintains that these graphics cards offer up to 38 percent energy savings compared to standard versions. Other models in this series are the Go! Green HD 4650 SCS, and Go! Green HD 4350 (non-HDMI).
